4.  Insert  the  chuck  wrenches,  as  shown  in 

Figure  25,  then  while  holding  the  spindle, 
unthread  the  chuck  in  a  counterclockwise 
direction.

5.  Support the chuck, unscrew it, and remove.

To remove the chuck:

1.  DISCONNECT LATHE FROM POWER!

2.  Use an appropriate device to protect the ways 

and support the chuck (refer to 

Installation & 

Removal Devices on Page 26).

3.  Remove  the  cap  screws  and  chuck  locks 

(see 

Figure 24).

Chuck Removal

Changing Jaw Set

The 3-jaw scroll chuck included with the lathe fea-
tures inside and outside hardened steel jaw sets 
(see 

Figure 26), which move in unison to center 

a concentric workpiece. 

When installing the jaws, it is important to make 
sure they are installed correctly. Incorrect installa-
tion will result in jaws that do not converge evenly 
and are unable to securely clamp a workpiece.

Jaws  are  numbered  from  1–3  (see 

Figure  27). 

They  are  designed  to  be  installed  in  numerical 
order in the jaw guides so they will hold a concen-
tric workpiece evenly.
